Great presentation by Bernard Traversat, Head of the Java platform development, at Oracle Code One 2018, San Francisco. Here are key points:
- Entire Big Data stack for storing data is written in Java (Hadoop, Spark, Kafka, Elastic Search, …)
- Java has enormous ecosystem of tools and libraries
- Enterprises run on Java
- Bringing new technology into enterprise (such as AI, ML) is a huge challange
because there is a lot to learn, and that gives Java and JVM huge advantage because enterprise allready knows Java and JVM. Technology needs to be understood by the enterprise. - Easy access and lower cost to develop, deploy and maintain:
- easy access to developers
- cost efficency (cost vs ROI)
- maintainability as the code size is growing and aging (thanks to code readability)
- Java is in the foundations of the cloud
- Incoming Java innovations for ML, AI and BigData (openjdk.java.net):
- Panama, more efficent replacement for JNI (faster and easier communication with GPU). Also the support for vector computing natively inside the JVM and Vector API
- Valhalla, new type system for more efficient manipulation with data in memory
- Loom, lightweight threads for massive parallel processing
- ZGC, order of magnitude better performance for memory management
- To conclude:
- Java is #1 Programming Language
- There are 12 Milion Java Developers
- 38 Billion active JVM-s
- 21 Billion cloud connected VM
